SPRINGVALE MT PIPER WATER TREATMENT FACILITY
In late 2017, Abergeldie was engaged by Veolia Water Australia under a design and construct contract, for the construction of a 14.8km Water Transfer Scheme from Springvale Mine together with a new Water Treatment Facility at Mt Piper Power Station to treat up to 48ML per day of water produced from mining operations for use in the power station.
Full scope comprises of:
- design, construction, testing and commissioning of a 14.8km pipeline (including a horizontal directional drill beneath the Castlereagh highway) and using existing pump stations to transfer mine water from the Springvale and Angus Place Mines to the power station;
- construction, testing and pre-commissioning of a water treatment facility adjacent to the power station to enable use of treated water by MPPS for cooling purposes, and release of surplus treated water to MPPS storage dam; and
- construction, testing and pre-commissioning of a new brine crystallisation system and salt slurry ponds at the power station to enable the efficient disposal of brine
Bulk earthworks to the Water Treatment Facility commenced in December 2017. During the first half of 2018, the Water Treatment Facility has progressed with construction of civil infrastructure comprising piled foundations, reinforced concrete water retaining structures, slabs and plinths, cladded buildings, and inground process pipework and electrical services.
During the same period, construction of the Water Transfer Scheme has commenced with installation of 2.5km of 710OD PE pipeline completed on the Newnes Plateau, and several kilometres of pipework trenched and installed in other zones. Concurrently, works have been progressing with the installation of an 880m horizontal directional drill to enable the transfer pipeline to pass beneath the Castlereagh Highway.
Abergeldie and Veolia Water Australia have adopted an integrated approach to delivery of the project. Over the next few months, mechanical and electrical works will ramp up at the Water Treatment Facility with the installation of major process equipment including Actiflo and Multiflo units, chemical and polymer dosing equipment, media filters, RO skids, lime and magnesium storage, dosing equipment, HV and LV electrical infrastructure.
Works to trench and lay the remainder of the Water Transfer Scheme will continue with the pipeline to be commissioned towards the end of the year.
